***Why doesn't Canon do something about the E18 error?***

Like what exactly? Loosen the lens mechanism tolerances even more so that a customer has to introduce bigger chunks of grit to lock up the lens? Use a higher torque lens drive motor in an attempt to chew-up or spit out obstructions? Use metal parts and rubber seals that add to the cost of the camera? Every meaningful suggestion has a down-side so, besides doing "something", what do you recommend?
In all probability Canon COULD improve reliability but that only makes sense if it's in their interest to do so. Given their excellent reputation, why would they do something to cut into both profits and sales (of replacement cameras)?

Backward engineer a Sony camera and see what they are doing. I think Sony have less problems with moving the lens.

But more problems with DUST ... the P150, P200 onwards had more CCD dust issues than your average 350D . I've yet to hear of a Canon which hasn't been abused with dust on the CCD, it's common with Fuji and Sony.

Do you mean "has been abused" or "hasn't been abused"? If "has", here's one:

If "hasn't" the sentence doesn't make sense.

I don't mean in the LENS, a lot of Gs (Mostly 3s and 5s) have some in and the Pro1 Lens was a right Dustmonster - I'm on about actually ON the CCD where it leaves big blobs on the images like a DSLR does ... Sony Are and Fuji were rife with it

Jojo Isip is talking about dust on the SENSOR which is the same as dust ON the CCD of his G7. Not his lens.

Yes - but how did the dust get on the sensor if not through the lens mechanism which operates like a bellows moving air in and out? That's the point - a tight fitting lens can jamb with grit while a loose fitting lens allows dirt to enter the sensor area. Which do you prefer?
Personally, I'd prefer a tight lens and just take care not to foul it with any dirt or debris.

I was just pointing out to Adam-T that Canon is not totally immune from dust on the sensor as he had implied to my statement the Canon should backward engineer the Sony cameras to see what they are doing right since thy don't have the frequency of lens-jamming (E-18 error) that Canon does.
With the necessary tolerance of moving parts, none is immune. It's just better to have one problem instead of two.

Does anyone rember what the original poster ask?
It is amazing how thread wander. I never read a threat with 25 responses because only the first five to eight are relevant.

The OP asked why doesn't Canon do something about the E18 error. Someone asked like what? I suggested Canon backward engineer a Sony camera and see what they do since they don't have nearly the problem. Someone said then Canons will have dust on the sensor problems. I said they already do. That's where we are at.

What post or discussion are you addressing with these questions? I don't see anything about tapping down hard.

I would assume that there are those who believe that a tighter fitting lens would solve the E18 error problem because there would be less chance of dust finding it's way into the mechanism.
The reason that Sony and others are not reporting this as a well known defect is exactly what Canon has ffinally done. The new cameras won't give out an error signal so the owners won't figure things out.
I'm sure the competition have the same problem, just less sales, no reporting of a common problem and no public acknowledgement of a prevalent flaw.
